About Us

Water doesn't recognize borders — and neither do the threats it faces. Our international teams work tirelessly to defend it.

This work is possible because of scientists like you. Your voice is essential.

Pollution doesn't stop at your neighbor's fence — and our solutions don't either. We work across generations to rebuild what was lost.

The water that flows through you connects you to 7 billion people — and countless ecosystems. Stand with us.

'Thirty years ago, this river was polluted. Through their work, native fish are returning. I watch the difference daily.' — Elder Maria

Pollution doesn't stop at your neighbor's fence — and our solutions don't either. We work across industries to solve problems at their source.
